1. INTRODUCTION

This document details the statistical analysis of the data that will be performed for the Italfarmaco S.p.A. study DSC/11/2357/43.

The proposed analysis is based on the contents of the Final Version of the protocol (dated 01 Aug 2012) and amendments 1, 2, 3, 4, 5, 6 and 7 (dated 05 Dec 2012, 25 Mar 2013, 23 Oct 2013, 17 Apr 2014, 16 Mar 2015, 06 Jan 2016 and 11 Apr 2017 respectively).

The Clinical Study Report (CSR) will be written by WCT following the guidelines in the ICH E3 document.

The efficacy and safety analyses will be performed by Worldwide Clinical Trials (WCT).

The pharmacokinetic (PK) analyses will be performed by Accelera.

The primary objectives of this study are as follows:

To establish the histologic effects of Givinostat administered chronically at theselected daily dose

The secondary objectives of this study are as follows:

To establish the effects of Givinostat administered chronically at the selecteddaily dose on functional parameters, such as the 6-Minute Walk Test (6MWT),North Star Ambulatory Assessment (NSAA), and performance of upper limb(PUL)

To establish the safety and tolerability of Givinostat administered chronically atthe selected daily dose in children with Duchenne muscular dystrophy (DMD)

To explore the effects of Givinostat administered chronically at the selecteddaily dose on parameters such as magnetic resonance imaging (MRI) andbiomarkers

To explore the acceptability/palatability of the oral suspension

To explore whether the effects of Givinostat on disease progression may berelated to the type of DMD mutation

Extension phase:

The primary objective is to evaluate the safety and tolerability of long-termadministration of Givinostat administered chronically at the selected daily dosein children with DMD.

The secondary objectives are:

To establish the effects of Givinostat administered chronically at the selecteddaily dose on other functional parameters, such as the 6MWT, NSAA, and PUL

To explore the effects of Givinostat administered chronically at the selecteddaily dose on parameters such as MRI

To collect information related to 2 biomarkers, LTBP4 and osteopontin genotype(at the beginning of Extension 2 only).

The analysis populations of this study are as follows (see section 6.3 for definition): Intent-to-treat (ITT) Population

Evaluable Population

Completers Population

Safety Population

PK Population

This is a 2-part, phase 2 study to assess the effects of Givinostat on muscle histologic parameters and on clinical parameters in ambulant children with DMD. The safety, tolerability, and pharmacokinetics of Givinostat will also be assessed.

Approximately 20 children will be enrolled in the study as follows:

The first 4 children will be treated at a low dose level of Givinostat. If none of the stopping criteria are met after 2 weeks of treatment at the low dose, the review team will determine the escalated dose level (i.e., intermediate dose level) to be used for the treatment of an additional 8 children who will be treated at the intermediate dose. The 4 children previously treated at the low dose level will also be switched to the intermediate dose level. If none of the stopping criteria are met after 2 weeks of treatment at the intermediate dose, the review team will determine the subsequent escalated dose level to be used for the treatment of an additional 8 children who will be treated at the high dose. All children treated at the intermediate dose level will be switched to the high dose level.

Once all 20 children enrolled during the Part 1 of the study have been treated for at least 2 weeks, the review team will determine the RD to be used in Part 2 based on the safety and tolerability profile observed and on the PK analyses. All the children enrolled will switch to the RD level, which will be administered for the subsequent 12 months of the study (Part 2).

The additional children (if any) will be enrolled during Part 2 of the study and will receive the RD of Givinostat for 12 months.

At 12 months, efficacy and safety analysis will be conducted. If the results show a positive effect on patients, and no safety concern is raised, then patients will continue study

treatment for another 12 months (Extension phase 1) to evaluate the safety and tolerability of long-term administration of Givinostat and to evaluate the effect of treatment on muscle function. If, on the other hand, the final analysis of the results of the first 12 months of treatment does not support a beneficial effect of Givinostat in DMD, the study will be considered complete and the patient will be asked to discontinue the treatment and return to the site for early termination assessments (within 2 weeks after the last study drug intake) and follow up assessments (within 4 weeks after the last study drug intake). This extension phase will be up to 24 months.

Since the histology results of the first 12 months of treatment are positive, a second extension phase is foreseen in order to allow the patients to continue a study treatment that supports a beneficial effect of Givinostat in DMD. The children on treatment in the Extension 1 will be asked to continue in the Extension 2 and will receive Givinostat at the same ongoing dose for a maximum of an additional 12 months. During Extension 2, the dose will be adjusted based on the weight of the children. This extension phase will be up to 36 months.

A third extension phase is foreseen in order to allow the patients to continue a study treatment that supports a beneficial effect of Givinostat in DMD. The children on treatment in the Extension 2 will be asked to continue in the Extension 3 and will receive Givinostat at the same ongoing dose for a maximum of an additional 16 months. During Extension 3, the dose will be adjusted based on the weight of the children. This extension phase will be up to 52 months.

2. SAMPLE SIZE

The sample size estimation was based on the following assumptions:

A minimum of 20 evaluable children will be enrolled in this study.

In part 1 approximately 20 children will be enrolled in Part 1 (dose-finding) of this study.

A sample size of 20 children from part 1 completing the treatment period of part 2 should provide 90% power (at a 2-sided alpha level of 5%) to detect at least a 12.5% increase in muscle fiber area% (MFA%) between pre- and post-treatment (which corresponds approximately to a 26% relative increase given the observed mean in the Desguerre1 publication of 48%), the “worst case” standard deviation of 16%, which assumes that there is no correlation within a subject in the muscle area fiber percentage between pre- and post-treatment. This sample size is based on a paired t-test and the assumption of normal distribution of MFA%.

3. RANDOMIZATION

This is a non-randomized trial, all subjects will receive study drug.

4. INTERIM ANALYSIS

After the first 20 baseline biopsies were collected, an interim analysis aimed at checking the real variability observed in the study was conducted: the within-subject standard deviation

of MFA% was calculated, the actual distribution of MFA% was checked and the final sample size was adjusted based on the observed standard deviation and actual distribution of MFA%. Results by Al-Sunduqchi2 and Guenther indicate that power calculations for the Wilcoxon test may be made using the standard t-test formulations with a simple adjustment to the sample size. The size of the adjustment depended upon the actual distribution of the data. They gave sample size adjustment factors for four distributions. These were 1 for the uniform distribution, 2/3 for the double exponential distribution, 9/π2 for the logistic distribution, and π/3 for the normal distribution. So depending on the actual distribution of MFA%, sample size re-calculation was based on a Wilcoxon Signed Rank test with the corresponding adjustment if the observed distribution of MFA% was not normal.

The resulted sample size was smaller than the original and included 19 enrolled subjects.

5. STATISTICAL METHODS

5.1 Continuous

For continuous variables, the number of non-missing observations, mean, median, SD, minimum and maximum will be presented. For all tabulations of change from baseline data, the 95% confidence interval (CI) for the mean will also be provided.

Individual raw data will be presented to the precision in which it is recorded. The number of decimal places to display for individual derived data will be determined by the scale of measurement using the following rules unless otherwise stated in Section 6.2:

No decimal places will be displayed if the smallest calculated value is ≥ 100;

One decimal place will be displayed when the smallest value is within the interval(10, 100), with 10 being inclusive;

Two decimal places are displayed when the smallest value is within (1, 10), with 1being inclusive; and so on for even smaller scale of measurement.

For both raw and derived data, means and medians will be displayed to one more decimal places, the individual data and dispersion statistics (e.g SD) will have two more decimal places, and the minimum and maximum will be displayed to the same number of decimal places as reported in the individual data. Change from baseline will be reported to the same precision as the observed values.

5.2 Categorical

Categorical data will be presented in contingency tables with cell frequencies and percentages for the subject population. Percentages will be presented to one decimal place and will be calculated using the number of subjects with non-missing data as the denominator unless otherwise stated. The number of missing data points will also be presented where applicable.

6. ANALYSIS PLAN

6.1 General

All statistical tests will be performed using a two-tailed 5% overall significance level, unless otherwise stated. The null hypothesis at all times will be that the pre-treatment and post-treatment values are equivalent. All comparisons between pre-treatment and post-treatment measurements will be reported with 95% CIs for the difference. For each statistical test, an observed significance level will be quoted. Where this value is less than 0.05, 0.01 or 0.001, attention will be drawn to the fact using the conventional “*”, “**” or “***” annotation, respectively. P-values will be rounded to four decimal places.

Normality assumptions will be evaluated by an examination of the residual plots and the Shapiro-Wilk test of normality. Depending on the degree of departure from these assumptions, an alternate nonparametric approach may be used for supportive purposes.

With the exception of some hematology parameters (see section 6.15.3), post-baseline repeat/unscheduled assessments will be disregarded, although they will be listed in the relevant appendices to the report, in particular all clinically significant values will be noted.

All calculations and figures for the efficacy and safety analyses will be produced using SAS® Version 9.3.

PK analyses will be performed using Phoenix WinNonlin Version 6.3.

All summaries and analyses documented below will be presented in the final integrated statistical/clinical report and tables that will be based on the E3 guidelines published by ICH. However, it is noted here that no analysis plan prepared in advance of the data can be absolutely definitive and so the final report may contain additional tables or statistical tests if warranted by the data obtained. The justification for any such additional analyses will be fully documented in the final report.

• MRIThe MRI results are centrally scored as ‘Stage 0’, ‘Stage 1’, ‘Stage 2a’, ‘Stage 2b’,‘Stage 3’, ‘Stage 4’ (please see ‘DSC_11_2357_43_MRIManual_Final_5Feb2013_final.pdf’ for further information). The frequency of theMRI scores at Baseline, End of Study and End of Extension 1 calculated andpresented per body location. Change in the MRI at End of Study/End of Extension 1is determined by comparing the MRI score given at baseline to the MRI score givenat End of Study/End of Extension 1.

• miRNAChanges from baseline to End of Study will be calculated for the followingparameters – miR-1, miR-133, miR-206.

• Changes in muscular functiono Change in muscular function based on the 6MWT at End of Study/End of

Extension phases is calculated as the difference between the distance after 6minutes (meters) at End of Study/End of Extension phases and its baselinevalue. If more than one value is recorded for the baseline, the mean valuerounded to the integer will be taken. Calculation method is specified insection 6.12.

(a) worst result observed in parts 1, 2 and the extension 1 for the extension 1analysis, and(b)≥ worst result observed in parts 1, 2, extension 1 and extension 2 for extension 2analysis.(c)≥ worst result observed in parts 1, 2, extension 1, extension 2 and extension 3 forextension 3 analysis.

For Time to Walk and Time to Stand up worst result is the maximal value, while for all other scores (excluding Total Score) worst result in the minimal value.

2) if missing not due to ambulation at visit x, then we impute using the mean ofpatients with values at visit x (and not the mean across all visits)

In addition, for missing values without reason of missing at Baseline, the mean of all baseline values will be imputed except subject 512 – “Time to stand up from floor”. For Subject 512, missing values for test “Time to stand up from floor” at baseline and post-baseline (e.g., 12 months) the worst value collected during the trial for this subject will be used for imputation.

Missing values of 'time to walk 10 m' and 'time to stand up from floor' were imputed according to whether the subject was ambulatory or not. If a subject was ambulatory then the result was imputed to the mean result of the specific visit, and if the subject was not ambulatory, the result was imputed to the maximal result collected. Missing score results were imputed to the minimal result collected. Missing 'Total score' was imputed as the sum of all non-missing score results per visit.

3) when both baseline and post baseline visit(s) values are both left or right censored,then the visit change from baseline will be set to missing

Such imputation necessarily leads to censored observations and therefore means and standard deviations will be estimated using PROC LIFEREG which provides a mechanism for handling right (and/or left) censored data when the underlying probability density function is Normal. In the absence of covariates, the mean is given by the intercept term and the SD by the scale parameter. See below for details.

- Identify the worst/maximum observed value (i.e., Time to stand up from floor(seconds)) from subjects with available data; apply this value to those patients willmissing data due to an inability to perform the task; identify these patients as rightcensored in the dataset in accordance with SAS PROC LIFEREGinstruction.. The SAS® code for this model is given below:

PROC lifereg DATA= Datasetname covout outEST=lifeout; MODEL y*cens(0) = / dist=normal; run;

The estimated mean and its standard deviation are the estimates of the intercept and the scale from following SAS output (i.e. 10.0021 and 4.4734 in this example, respectively).

- Identify the worst/minimum observed value (i.e., 6MWT) from subjects withavailable data; apply this value to those patients will missing data due to aninability to perform the task; identify these patients as left censored in the datasetin accordance with SAS PROC LIFEREG instruction. The SAS® code for leftcensoring is given below:

DATA leftcensored; set data; if y=. then do; lower=.;y=minobs;end; else lower=y; run;

PROC lifereg DATA=leftcensored covout outEST=lifeoutleft; MODEL (lower,y) = / dist=normal; run;

- Identify an interval data for change from baseline (i.e., 6MWT, time to walk 10mand time to stand up from floor) in accordance with SAS PROC LIFEREG withinterval censoring to estimate mean and standard error. The SAS® code for leftcensoring is given below:

PROC lifereg DATA=CHG; MODEL (low, up) = / dist=normal;

run;

For the NSAA scores the missing score is imputed with worst score, missing NSAA ‘Total Score’ observations were imputed as the sum of all test results per visit, regardless of whether the subject was ambulatory or not.

Incomplete datesAll incomplete dates will be entered on the database as they were recorded in theCRF. Thereafter for calculation purposes only, the incomplete dates will becompleted using pre-defined rules. If a day or month is recorded as NK or NA itwill be replaced by the first day of the month or January respectively, provided thisdoes not contradict any other dates recorded. For missing adverse events (AEs) andmedications dates/times during the trial, the worst-case date will be used (e.g. theend of the month for a stop date and 23:59 for the stop time, the date/time of initialdose for start of AE i.e. all events with missing start dates will be assumed to betreatment emergent).

In the case where a variable is recorded as “>x”, “≥x”, “<x” or “≤x”, then for analysis purposes a value of x will be taken. Where a range of values is quoted the midpoint of the range will be taken. In the case where a subject records more than one score at a timepoint for any particular efficacy measure, the worst of the recorded scores will be taken for analysis purposes.

ECG dataFor ECG data recorded on continuous scales, if more than one value is recorded, themean value rounded to the integer will be presented. For overall interpretation ifmore than one value is recorded, then take most severe of the respective readingswill be taken.

o QT IntervalsThe analysis will use QT intervals that have been corrected for heart rate by the Bazett’s1 and Fridericia’s2 formula (QTcB = QT/ [RR]1/2 and QTcF = QT/[RR]1/3 respectively), as recorded on the CRF.

Pulmonary function tests (PFTs)For PFT data recorded on continuous scales, if more than one value is recorded, themean value rounded to the integer will be presented

Secondary Efficacy AssessmentEfficacy will be assessed through paired t-tests to test the changes from baseline inbiopsy at End of Study and through descriptive statistics of changes from baseline inthe MRI, 6MWT, PUL, and NSAA at End of Study and Extension Phases.

BMIBMI will be calculated using the following equation –

BMI (Kg/m2)=weight(kg)/Height(meters)2

6.3 Analysis populations

The intent-to treat (ITT) population will include all children who are enrolled in the Part 1 portion or entered the Part 2 portion of the study. Subjects will be analyzed according to the dose level to which they are allocated.

The Completers population will include all children who successfully completed Part 2 portion of the study. Subjects will be analysed according to the dose level to which they are allocated.

The evaluable population will include all subjects who are in Part 2 of the study, receive Givinostat of at least 80% dose in Part 2, have at least one baseline and one post-baseline assessment of biopsies, and have no major protocol violations. All protocol deviations will be assessed and documented on a case-by-case basis prior to the database lock, and deviations considered having a serious impact on the efficacy results will lead to the relevant subject being excluded from the population. Major protocol deviations include (but are not limited to):

Not meeting inclusion criteria/meeting an exclusion criteria

6.15.2 Adverse Events

A treatment emergent adverse event (TEAE) is defined as any AE that has an onset on or after the dose of study treatment, or any pre-existing condition that has worsened during or after the first dose of study treatment. Whether TEAEs will be attributed to a treatment or not is a clinical decision based on all available information at the time of the completion of the eCRF.

A treatment-related adverse event is defined as an adverse event as being unlikely, possibly, probably or definitely related to the study treatment. If adverse event has missing relationship it is assumed to be related to the study treatment for analysis purposes.
